<h3>Assemble a Configuration Object for a POST Transaction</h3>
<p>The IO configuration object support allows you to designate the transaction method (<code>POST</code> in this case) and other information, including data that should be sent as the POST body:</p>

<h3>Create Handlers to Process Successful and Unsuccessful Transactions</h3>

<p>Our handlers for the events that fire on successful and unsuccessful responses will write out information about the transaction to the <code>innerHTML</code> of an element on the page:</p>
